摘要
紧邻既有线增建二线施工必须严格保证既有线行车安全,爆破开挖石方因受行车干扰,施工工效显著降低,行车干扰费大大增加。该文从不同的爆破施工方法、不同的线路情况对增建二线爆破开挖石方受行车干扰的范围作细致的分析,提出一种既符合现场施工实际,又具有可操作性的范围划分方法。
When build a second line adjacent the existing one, it is very important to strictly secure the safety of the existing transportation. In this case, the blasting rock move construction will be very much interfered by the transportation, its work efficiency will be decreased a lot and the interfere fee will increased a lot. This paper makes an analysis to the interference range for different blasting method and existing line. It gives out an practical method to demarcate the interference range.
